Neo4j replication option for Neo4j Enterprise?

Question

It seems that the high availability of Neo4J is only available for the released Enterprise version, is there any other alternative for replication without this module? (i.e. no cost). Thanks for any help!

Answer 1

The enterprise is available as quid-pro-quo - if you expose your code under an open source license, then you get free access to the free Neo4j Enterprise. However, if you are closed, Neo Tech charges a license fee. This fee is determined by your needs and your ability to pay - if you are a small outfit without venture capital, it is still free, and then the licensing cost increases as your ability to pay for the development of Neo4j increases.

If your application is open source, as you mentioned, then you can use Neo4j Enterprise without paying for it, just upload it to neo4j.org.

Answer 2

In fact, Neo4j Enterprise is free under the open source license AGPLv3.

Neo4j Inc cannot change the terms and still call AGPL.

If you use Neo4j Enterprise as a server (like most people) and communicate with it through your REST API or any official BOLT drivers, you never run the AGPL API copy requirement.

In other words, the software that connects to it does not have to be open source.

You can download Neo4j Enterprise licensed open source binary files up to version 3.2.x from dist.neo4.org. Links for windows and unix packages are provided below. (Replace version number for specific versions)

http://dist.neo4j.org/neo4j-enterprise-3.2.8-windows.zip

http://dist.neo4j.org/neo4j-enterprise-3.2.8-unix.tar.gz

If you want Neo4j Enterprise 3.3.0 and get a free open source license under it, then you can build them from the source, as we do for our customers from the US government, or simply grab them from our free distribution site.

Post a blog post if you want to understand why this happened.
